摘要： A switching system for breaking a current, including a contact arrangement having a first and second terminals, a resonance circuit connectable across the contact arrangement, In the closed state the first switch enables current to flow through the resonance circuit in a first flow direction and into the contact arrangement in a direction opposite to a contact arrangement arc current flow direction. A second switch connected to the resonance circuit and to the second terminal. In the closed state the second switch enables current to flow through the resonance circuit in a second flow direction opposite to the first flow direction. A control system arranged to alternatingly set the first and second switches in the closed state and then in the open state upon a current breaking operation, until a current pulse, emanating from energy supplied by a contact arrangement arc current, flowing through the resonance circuit and into the contact arrangement reaches an amplitude which is equal to or greater than a magnitude of a contact arrangement arc current.

摘要： The invention discloses a quick arc-breaking circuit-breaker, comprising two electrode contacts for switching on and switching off a circuit, and a plurality of partition plates arranged between the two electrode contacts and configured in such a way that, when the two electrode contacts are separated, the partition plates are inserted at the fastest speed between the two electrode contacts, to quickly break the arc and stop burning. As the partition plates of the quick arc-breaking circuit-breaker are inserted between the two electrode contacts from different directions, the breaking and insulating speed is accelerated, the isolation and sealing effects between the two electrode contacts are enhanced, and the insulation and arc extinguishing effects of the circuit-breaker are thus improved. The circuit-breaker of the invention has a simple structure and a low manufacturing cost.

摘要： A power circuit breaker unit has first and second arcing contact pieces. A contact gap is formed between the arcing contact pieces. A switch gas channel of the circuit breaker unit joins the contact gap to the surrounding area of the circuit breaker unit for removing a switch gas from the contact gap. Several barriers that increase a flow resistance are arranged successively, spaced from one another, in the switch gas channel. At least one of the barriers is arranged between a first pipe section, which is surrounded by a second pipe section, and the second pipe section.
